The operating instructions must be read carefully before using the product and must be kept
on hand for later reference.
1.2 Explanations of Symbols
• Safety precautions and warnings are emphasized by means of symbols and attention-getting words.
• Safe use of the product is only possible if these safety precautions and warnings are adhered to.
The safety precautions and warnings are laid out in accordance with the following principle:
ATTENTION-GETTING WORD!
Type and Source of Danger!
Possible consequences in the event that the hazard is disregarded.
• Measures for averting the hazard.
The meanings of the attention-getting words, as well as the scope of the associated hazards, are listed
below:
DANGER!
This word indicates a hazard with a high degree of risk which, if not avoided, results in death
or severe injury.
WARNING!
This word indicates a hazard with a medium degree of risk which, if not avoided, may result
in death or severe injury.
CAUTION!
This word indicates a hazard with a low degree of risk which, if not avoided, may result in
minor or moderate injury.
ATTENTION:
This word draws attention to a potentially hazardous situation which, if not avoided, may
result in property damage.
NOTE!
A note draws attention to useful tips and suggestions, as well as information regarding
efficient, error-free use.

2. For Your Safety
2.1 Use for Intended Purpose
The product is based on the following functional principle:
Safety Light Curtain
The Safety Light Curtain monitors the safety field between the emitter and the receiver. If the safety field is
interrupted by an obstruction, a switching command is triggered. This switching command either prevents
initialization of a hazardous machine motion, or stops an action which has already been started.
Use of the Light Curtain is only permissible if:
• Hazardous motion can be stopped by electrical means using the light curtain’s safety output
• Adequate detection of possible obstruction is assured with existing resolution
• Use of a type 4 Light Curtain with performance level PL e is permissible
This product can be used in the following industry sectors:
• Special machinery manufacturing • Electronics industry
• Heavy machinery manufacturing • Glass industry
• Logistics • Steel industry
• Automotive industry • Printing industry
• Food industry • Aviation industry
• Packaging industry • Construction industry
• Pharmaceuticals industry • Chemicals industry
• Clothing industry • Agriculture industry
• Plastics industry • Alternative energy
• Woodworking industry • Raw materials extraction
• Consumer goods industry • Other
• Paper industry
2.2 Use for Other than the Intended Purpose
• The product is not suitable for use in potentially explosive atmospheres.
• Only accessories supplied or approved by wenglor may be used with the product.
DANGER!
Risk of personal injury or property damage in case of use for other than the intended
purpose!
Use for other than the intended purpose may lead to hazardous situations.
• Observe instructions regarding use for intended purpose.

2.3 Personnel Qualifications
• Suitable technical training is a prerequisite.
• In-house electronics training is required.
• Technical knowledge and experience concerning use of the guard is required in order to assure correct
evaluation of the safe working status during assembly, initial start-up and electrical installation.
• Trained personnel must have uninterrupted access to the operating instructions.
CAUTION!
Risk of personal injury or property damage in case of incorrect initial start-up and
maintenance!
Personal injury and damage to equipment may occur.
• Adequate training and qualification of personnel
2.4 Modification of Products
NOTE!
Modification of the product is impermissible.
Non-observance may result in loss of the CE marking and the guarantee may be rendered
null and void.
2.5 General Safety Precautions
NOTE!
• These instructions are an integral part of the product and must be kept on hand for the
entire duration of its service life.
• Read the operating instructions carefully before using the product.
• Protect the sensor against contamination and mechanical influences.
• Additional measures may be necessary in order to assure that the ESPE does not fail in a
dangerous fashion due to other types of light which are used in a special application (e.g.
resulting from the use of cordless controllers on cranes, emission due to welding sparks
or the effects of stroboscope lights).
